ISRAEL KIN-REY, OF WINDSOR, ONTARIO, CANADA.

PIPE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 271,250, dated January 30, 1883,

Application filed November 21,1882. (No model.)

To all whom it may concern Be it known that I, ISRAEL KINNEY, of Windsor, county of Essex, Dominion of Canada, have invented a new and useful Improvement in Pipe-Gutters; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which-it pertains to make and use it, reference being bad to the accompanying drawings, which form a part of this specification.

My invention consists in the combinations of devices and appliances hereinafter specified,

' and moreparticularly pointed out in the claims.

In the drawings, Figure 1 is a view illustrating my invention. Fig. 2 represents a variation in which there is a double cutter, bot-h cutters being straight. Fig. 3 represents another variation in which a circular cutter is. employed. Fig. 4 represents my invention arranged upon the principle of a pair of tongs.

It is the object of my invention to produce a pipe-cutter which shall cut the pipe by roll- -'ing it along a cutting-edge instead of drawing one past the other; and my invention consists more particularly in the combinations of parts necessary for accomplishing this result.

I am aware, at the outset, that it is not new to arrange a pipe-cutter with a cutting disk or wheel caused to impinge against the pipe, and operating by pressure instead of with a drawing cut. I do not therefore claim broadly'any pipecutter in which the cut is made by the principle of pressure in contradistinclion to a drawing out.

I will now proceed to describe my invention.

A is the body of my pipe-cutter. B is a sliding block, governed by an adjusting-screw, (J. D is a cutting-blade. E are anti-friction rollers upon which the blade rests. The blade may rest directly upon the rollers, or, in order to give the blade a greater bearing upon the rollers. it may rest in a block and this block have its bearing on the rollers. Frepresents a section of pipe that is being cut.

The operation of my device is as follows:

The device having been engaged over the pipe, as shown, the blade is forced in against the pipe by the pressure of the screw. As the wrench is now turned about the pipe the pipe will cause the cutter to .move longitudinally,

as shown by the dotted lines. The cuttingedge of the knife will act by direct pressure, and not by a drawing out, to sever the pipe. This pressure, as will be seen, is applied normally between the two rollers E. When the wrench has been turned so far as to shift the cutter-blade to the extremity of its stroke the motion may be reversed, and thus cause the blade to travel in the opposite direction. The blade shouldbe of such a length that in turning the wrench every part of the circumference of the pipe shallbe brought into contact with the cuttingedge before it is necessary to reverse the wrench.

This device may be considerably varied without departing from the principle of my invention. .For instance, in Fig. 2, there may be two cutting-blades, D, one above the pipe and one below it, both blades, or their blocks, riding upon anti-friction rollers, as shown. So, also, as shown in Fig. 3, the device may be provided with a single shifting-blade, but that blade be made circular, in the form of an open ring. This would be applicable only where the wrench could be passed on over the pipe; but it possesses the advantage of being continuous, so that-the wrench may be always moved in one direction, if desired, until the pipe is severed; or, as shown in Fig. 4, the device may be made in the form of a pair of tongs, in which case, of course, the adj ustto slide upon anti-friction rollers; or its block D may have the rollers E journaled directly to the block, thus constitutinga carriage which may travel along the way 1) as the wrench is revolved about the pipe. In this latter case it is apparent that the pipe will change its position toward and from the axis of the tongs as the device is operated.

I have described this device simply as'a pipe-cutter; but it is apparentthat it is equally well adapted, and my invention contemplates its employment, for the purpose of cutting pipes, rods, wires, or other round articles.

The circular cutter shown in Fig. 3 is not only in the nature of an open ring, but the ring itself may be provided with an opening through it at some point, as shown by the dotted lines, in order to permit a rod or pipe to enter between the jaws without the necessity of putting the cutter on over the end of the pipe.

What I claim is- 1. A pipe or rod cutter provided with one or more blades arranged to engage the pipe and to slide in the direction of its length upon rollers when the implement is turned around a pipe which is engaged by said blade or blades, substantially as described.

2. A pipe or rod cutter provided with a pair of jaws, either or both of which carries a blade arranged to slide longitudinally upon rollers, one ofsaid jaws being adapted to be adjusted toward'the remainingjaw, so as to cause the pipe to be gripped, substantially as described.

3. A cutter for pipes and rods, 8250., consisting of a stationary and a movable jaw, between which the article to be cut is engaged, 20 the movable jaw provided with mechanism for feeding it toward the other jaw, and a sliding cutter located in the movable jaw and supported upon rollers, the construction being such that as the implement is rotated about 25 the pipe or rod the cutter will be shifted longitudinallyupon the rollers, substantially as described.

In testimony whereof I sign this specification in the presence ot'two witnesses.
